between the side walls 6 and 7, thus giving a ocket of peculiar form.

he object and purpose of the pockets is create a suction effect which gives adhesion to the belt with reference to the pulley as the" ocket reaches a full contact therehe pockets are also designed with the advance points to the oblique walls 8 and 9, and the walls 10 and 11, so that the suction will be broken gradually but thorou hly as the belt passes away from the ulley. This arrangement gives a smooth, rm action between the running belt and pulley, and yet provides for easier release of the belt after it has performed its driving function.

It will be observed that in arranging the suction pockets all of the walls 6, 7,.are

parallel in the adjacent series of pockets,

and these walls lie inthe elemental longitudinal lines of the belt.

It will also be observed'that the end walls of the pockets in the various series are all in parallelism and, being oblique to the side walls, tend to guide the belt along the ele mental lines defined by the. side walls so that there is practically no side slippage of the belt with reference to the pulley.

' As illustrated, the various series of pockets are arranged in longitudinal rows or series and in transverse rows or series, and to clearly exemplify the invention, the transverse rows of pockets are all in parallel throughout the extended belt. Such an arrangement provides for the gripping action.

of the cups upon the pulley with each transverse line or row of cups coming in contact with the face of the pulley, and further provides for the ready release of each transverse line or row of cups at the point where the belt is free from the pulley. There is, therefore no overdrag of the belt with reference to the pulley inasmuch as when the suction cups'are vented and released the adhesion to the pulley is broken. Thereupon, the belt acts as the ordinary solid belt.

It is quite obvious that the belt- 9 K made in any desired form, either of uniform thieknessof leather or webbing or may be phed up? It is also apparent that the cups may be pressed into the face of a single piece or composition belting or may be formed through the laminae of certain strata of a composite structure. In fact, the

. principal idea is to provide in the working face of the belt a series of suction cups which will, upon contact with the pulley, give immediate adhesion and, upon-release of the belt from the pulley, break the suction, the cups being of a form which will centralize the belt with reference to the pulley.

side wall In Fig. 3 the relief of the suction iind release from the pulleyis illustrated. In this view the point 12, has passed beyond: the tangential point of contact and broken the suction of the cup with reference to thefate of the pulley.

It is obvious that the exact form and arrangement of the cups might be modified to anydesired degree without departing from the spirit or intent of the invention and that the cups may be formed in the belt in any desired manner. Of course, the illustration exaggerates the size, depth, etc., of the cups with reference to the belt, but actually the cups are so arranged that they do. not materially Weaken the belt structure.

What I claim as my invention and desire to secure by Letters Patent is: V v

1. A belt having a series of cups arranged transverselv and longitudinally of the belt and upon its face, and adapted to have contact with a pulley whereby adhesion between the belt and pulley is increased.

2. A belt having traction cups arranged in parallel lines lengthwise of the belt and in parallel lines transversely thereof.

3.,A belt having traction cups arranged longitudinally and transversely of said belt in a, series of rows, said traction cups having parallel sidewalls extending longitudinally I said cups having parallel side walls ar ranged longit inally of the belt and provided with en walls obliquely disposed to the side walls, two of said end walls projecting beyond the side walls and two of said end walls projecting between the side walls,

5-. A belt having suction cups arranged longitudinally and transversely thereof, each of said cups having substantially parallel side walls extending longitudinally of the belt and provided with end walls, one end wall projecting beyond the limits of the side walls and the other end wall projecting between the said side walls, the end walls being parallel with reference to each other.

6. A belt having suction cups arranged in the driving face of the belt, said cups hav-' ing parallel side walls and angularly dis: posed end 'walls, the angularly disposed walls meeting centrally with reference to the side walls, the end walls at one end pro jecting beyond the side walls, the end walls at the opposite end projecting between the l PERRY G.
